EPSON EH-TW650 - won't power on

Metin:

I got hold of this EPSON EH-TW650 which won’t turn on.
Inserting the power cable, you can hear a whine from the power supply as it powers up for about 10 seconds before that is replaced with a higher pitched whine from then on. Power/status LED’s don’t light up, the fans don’t run, the lamp does not power up.
When I first received this projector, I stripped it down to take a quick look and put it all back together, and it turned on! It stayed working for a few days until one day during operation it died again.
What I have tried so far:
* I have replaced the power supply entirely as I believed it was not providing power properly to the board (replacement power supply shows exact same behaviour as previous one)
* Searched the processor board over and over again for obvious bad caps with a multi-meter (I am an absolute novice at this, so it’s possible that the board is shorting or something and I just can’t find out where). Part of me wants to doubt it’s the processor board simply because it was working totally fine just a few days ago
+
What is most likely to be the problem? I’m most confused because after my first strip down the projector started working again totally fine. I should mention that when it died again after my first strip down I was moving the projector and believe the power cord shifted slightly, which is when it died.
Note: I have tried powering the projector on with the lamp cover on etc… as I know that the projector won’t power on without the cover. The fans/status lights should power on whether or not the lamp cover is attached.
